Beginning 3D Game Programming

Before you finish this chapter, you implement the camera class. During the Blockers game, you handled all the camera movements (mainly the view transform) on your own. Although it is a completely viable option, it can be a little annoying. Having an abstracted camera class is more natural. Create a new code file (call it camera.cs) in your project, and use the code from Listing 13.11 for the initial implementation.
